Here are more pics from last night. I woke up this morning and the spot was fine. If it was ick would it visually clear overnight? My water is always pristine and my temp is 82. I feed nls thera a. It is still being kind of reclusive but it may be bc it is the second biggest Acei in the tank. Appetite seems fine still and he comes out when I approach the tank. The spot seemed to be bigger than the pics i see online so idk. More opinions please. I need to know if I should start the heat / salt treatment.
